Mine is the tall deck (9.56), 59 degree lifter bore, 360 main block
which has p/n P4876797 if I remember correctly. I'm thinking 4-in
stroker crank, forged pistons in the 8.5-9.5 range depending on if I
ever boost it, 4.00 in std-bore (is 3.98x as delivered) forged pistons,
and first stock magnum heads w/P5249816 MPI intake then maybe W2-W8 and
matching intake. Megasquirt -n- spark for engine management of course 8).
I need to put my LA 360, Magnum 318/360, and R3 blocks side by side so I
can doublecheck accessory, motor, etc. mounting positions. Now that
would make a nice pic huh?

These are MP's A-engine race blocks. There are tall deck and short deck
versions plus full water-jacket and siamesed-bore versions. Two of these
are (were?) two 360 versions, both obviously tall deck (9.56") and have
full water-jackets. One is the 2-bolt main (P4876797) and the other is
a 4-bolt main which I believe has been discontinued. These real race
blocks have thicker decks and bore-walls, filled pan rail and bulkheads,
etc. thus making them stiffer and keeping the bore-walls straight and round
at wot (thus more power production).
